Sign meant to indicate the status of the dish washer (Dirty/Washing/Clean). We use it at work so that the staff using the kitchenette know whether they need to put their coffee mugs in the appliance, look for it there or, most importantly, not try to open the dish washer while it is working.
This is an upgrade of my former design ( https://www.thingiverse.com/thing:3095372 ). It features stronger "legs" and can be built without supports.
The whole object can be scaled to fit different handle thicknesses.
